Be it known that we, OTTO S'rmnn, a citizen of the Swiss Republic, and resident of Bern, Switzerland, ALFRED HAUSWIRTH, a

6 citizen'of the Swiss Republic, and resident of Bern, Switzerland, and 'ALFoNs Giants, a citizen of the Swiss Republic, and resident of Basel Switzerland, have invented new and useful Vitamine Preparations and 10 Processes of Making Same, of which the following is a full, clear, and exact specification.

Our invention relates to the manufacture of a vitamine malt preparation which contains in durable form'not only the vitamines stable 'to heat and storage, but also those labile to these influences.

It is known that the preservation of vitamines and materials containing vitamines depends on numerous factors. In many cases, as for instance in the case-of the antiscorbutic vitamine, heating for a short or long period to a more or less high temperature, (for instance 60-7 0 C.) 'or even drying or standing at room temperature, suifices to destroy the activity to a great part or completely (of. Holst & Frolich, Zeitschrift fiir Hygiene Vol. 72. 1. 1912 and Vol. 75. 334. 1913).

The methods hitherto known for the preparation of malt extracts did not take into account these facts, temperatures rising up to 701()0 being usual in the course of their preparation, be it in the preliminary treatment of the amylaceous materials and of the malt used, be it in the diastatic process itself or in the final concentration of the extracts.

By these processes any vitamines of thermolabile character which may have been 40 present in the starting materials are of course more or less completely destroyed.

We have found, that it is possible tofobtain vitamine malt reparations containing not only the vitammes stable to heat an storing, but also those labile to these influences, if the mashing and saccharifying process of the amylaceous material are con ducted in presence of a small quantity of non-toxic, polybasic or anic acid and at a tem erature below and if the concentration of the thus obtained malted product is'also effected in the resence of a small quantit of the said aci and at a temperature be ow 60 C.

an acid substance we use particularly I citric or tartaric acid, but it is evident, that any other non-toxic polybasic organic acid may be employed. To attain the scope of our invention we employ preferably a quanfeebly acid to congo. However, even smaller quantlties may be serviceable for the purpose. If desired, the acid may be partly neutralized at any suitable stage of the concentrating operation, as in every case the achieved new vitamine malt preparation must contain at least traces of the free polybasic organic acid employed.

As an amylaceous material especially adapted for the purpose of our invention we use chestnut-meal. This material which has not been employed before for preparing malt extracts, possesses the advantage of not only being rich in 'vitamines but also imparting to the malted product a very good flavour. Instead of chestnut-meal alone other vitaminous starchy materials or mixtures of the latter with chestnut-meal 'may be used.

Thesaccharification is effected with fresh so green malt, rich in the antiscorbutic vitamlne, instead of with kiln-dried malt, the

vitamine content of which isdestroyed or reduced to a minimum by the process of its preparation.

The malted extract resulting from the saccharification process may be concentrated to the usual sirupy consistency or to complete dryness.

We are aware of the fact that the evaporation or thickening ofmalt extracts at temperatures below 60? C. has already been effected, but heretofore this evaporation or thickening has never been effected in the presence of a small quantity of free polybasic organic acid and with malt extracts obtained by mashing and saccharifying the .amylaceous material in the presence of small quantity of such an acid.

The malt extract obtained by our process, is especially adapted, by its high content of vitamines of different kinds, for the treatment of various avitaminous diseases. By its nutritional value and its content of diastase, further by its good taste and excellent wholesomeness, it is also of great value of a reconstituent and tonic for reconvalesoents a. s. 0

groundjresh green malt and water in resence of about 0.1 percent of'citric aci and a preservative; such as toluene, with continu= ous uniform stirring for several days. The whole is then filtered and concentrated in a vacuum and a low temperature to the desired degree of consistency.
